District Crews Lay Last Block-Will Become 'No. 1 Experiment'
A project of vital importance to Imperial Valley agriculture, the installation of the tile drainage system at the Meloland experiment station, was completed Monday, as irrigation district crews put down the last block of 13,000 feet of tile.
Because drainage has become one of the principal problems of county agriculturalists, the drainage project will become the No. 1 experiment at the Meloland station, according to L. G. Goar, station superintendent.
Tile lines were installed in various spacings, ranging from 80 feet to 400 feet. Tests will be made to determine which spacings provide adequate drainage.
Manholes and permanent test wells have been installed to permit frequent sampling and testing of water for quality and ground movement, Similar checks will be made to determine chemical changes in soil under different spacings.
Crop yield records will also be checked.
Goar pointed out that the Meloland station was selected for the experimental tile drain project because the station had a steadily rising water table and the accompanying rise of alkali, and because the station soils are of a clay classification, representative of approximately 70 per cent of the total agricultural lands of the valley.
